You cannot work out x - 2y = 1 since this all depends on the values of x and y! If you are referring to "graph the function", then...
(2x)ysquared
Whooop!
It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.
You will get nonsense. You cannot plug x2y + 4 into anything!
x2 + y2 = 1x2- x2+ y2= 1 - x2y2 = 1 - x2y =± √(1 - x2)
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8
To find the greatest common factor of x^2y and xy^2, we need to determine the highest power of each variable that is common to both terms. In this case, the common factors are x and y. The highest power of x that is common to both terms is x^1, and the highest power of y that is common to both terms is y^1. Therefore, the greatest common factor of x^2y and xy^2 is xy.
xy
The GCF is xy
Probably not, though it is hard to work out the mapping "r equals 1 2"
